SUPERBRIGHT 15% Vitamin C Serum Stick

The base most products are built on. It carries the other ingredients and has no safety concern.

A lipophilic derivative of ascorbic acid (vitamin C) designed for stable delivery in cosmetic formulations. It is graded low concern and well tolerated, with benefits similar to other vitamin C esters.

A linoleic-acid-rich plant oil used as an emollient and, in some small pediatric studies, associated with support of the skin barrier when applied to infant skin. It is well tolerated with a low reported rate of contact reactions.

A synthetic polymer used to thicken and stabilize cosmetic formulas. The polymer chains are too large to penetrate skin; graded safe by the Cosmetic Ingredient Review and widely used in rinse-off and leave-on products.

A lightweight humectant and solvent similar in role to propylene glycol, used to carry actives and give lotions a lighter feel. CIR has reviewed it and considers it safe as used in cosmetics.

A stearic acid derivative used to thicken and stabilize formulations while providing mild emollient properties. Graded low concern with no documented sensitization or safety issues.

A diester formed from malic acid and isostearyl alcohol. It conditions and smooths skin with no known safety issues in cosmetic use.

Derived from olive oil fatty acids, this PEG-free emulsifier is used at low concentrations to hold water and oil phases together in creams. Available safety and dermatological testing has not shown meaningful irritation or sensitization at use levels.

Used in tiny amounts to set a product to skin-friendly pH. No concern at those levels.

A plant-derived antioxidant found in seeds and grains, used in cosmetics to protect against free-radical damage. Published safety assessments grade it low-concern and it is generally well tolerated across skin types.

Sodium PCA is a natural component of skin's own moisturizing factor and is used in cosmetics as a humectant to help skin hold onto water. It has an extensive history of safe use with no meaningful irritation or sensitization signal.

An antioxidant that helps protect a formula and condition skin. Well tolerated.

Gluconolactone is a polyhydroxy acid that exfoliates gently while also acting as a humectant and mild antioxidant, and it is generally recommended for sensitive or barrier-compromised skin over smaller AHAs. A full cosmetic panel review found it safe as used, though some users still report mild stinging or redness at higher concentrations.

An olive-oil-derived emulsifier, almost always paired with cetearyl olivate, that holds water and oil together and leaves a light skin-like finish. It is well tolerated and graded low concern in published assessments.

The sodium salt of benzoic acid, used as a preservative in both foods and cosmetics. Decades of safety review support its use at typical cosmetic concentrations, with mild irritation the main reported issue in sensitive skin.

A mineral salt used in cosmetics as a pH buffer and conditioning agent. Safety data indicate no hazards or sensitization concerns for topical cosmetic use at typical concentrations.
